Emmanuel Joseph Raphaël Orazi, known as Manuel Orazi, was an art nouveau illustrator and poster artist. He was born probably in Rome in 1860 and died in Paris in 1934. In 1895 he created the Calendrier Magique which was an occult-themed calendar. It was limited to 777 copies and was made in collaboration with Austin De Croze. He also illustrated novels such as Aphrodite by Pierre Louÿs, Ma petite ville by Jean Lorrain in 1898 and Les Fleurs du mal by Baudelaire. He made jewelry designs that were displayed at Maison de l'Art Nouveau in 1896. His jewelry designs were also sold at La Maison Moderne. For her theater at the Universal Exposition in Paris in 1900, Loie Fuller commissioned Orazi to create the poster, which was printed in three editions and three color schemes.

In 1921 he designed the sets for the silent film L'Atlantide.
